Anything received after that time might be too late.
I think I'm seeing a regression here in the amdgpu driver, though not
being a kernel dev I could be wrong.
I built and booted this today on an x86_64 machine (AMD Ryzen 7 3700X,
Gigabyte X570 UD motherboard) with 3 x AMD graphics cards (using names
from lspci output):
- Cape Verde GL [FirePro W4100]
- Oland XT [Radeon HD 8670 / R5 340X OEM / R7 250/350/350X OEM] (rev 83)
- Bonaire [Radeon R7 200 Series]
All three using the amdgpu driver (radeon module blacklisted).
This machine has been running vanilla 5.15 stable releases for a good
while, with the kernel updated with whatever the latest 5.15 release is
every 6 weeks or so. Never had any amdgpu problems.
To build 5.15.107-rc1 I applied the contents of the queue-5.15 directory
on top of 5.15.106, having synced the stable queue git repo up until
commit 344d8ad1b5dde387d1ce4d1be2641753b89dd10d (still the latest commit
as a type). This is what I have done for years running vanilla stable
kernels.
There was nothing out of the ordinary in the build output, but on
rebooting into 5.15.107-rc1 I had the following error in dmesg from 1
card only:
amdgpu 0000:0d:00.0: [drm:amdgpu_ib_ring_tests [amdgpu]] *ERROR* IB test
failed on vce0 (-110).
[drm:process_one_work] *ERROR* ib ring test failed (-110).
This was during bootup immediately after driver loading. X is not
running. 0000:0d:00.0 is the Bonaire card.
I then shutdown and fully powered off for a few minutes, booted
5.15.107-rc1 again, but the error on that card persisted exactly the same.
This was a regression for me as I've never had that error before on any
kernel release (I grepped through old kernel logs to check).
I then rebuilt 5.15.107-rc1 but without applying the following 4 patches:
drm-panfrost-fix-the-panfrost_mmu_map_fault_addr-error-path.patch
drm-amdgpu-fix-amdgpu_job_free_resources-v2.patch
drm-amdgpu-prevent-race-between-late-signaled-fences.patch
drm-bridge-lt9611-fix-pll-being-unable-to-lock.patch
On booting into the newly built kernel there was no error anymore,
amdgpu dmesg output was as normal, and the machine is running fine now
on that.
So I'm quite confident one of those patches introduced the error for me.
Having now looked at the contents of them I see the lt9611 is entirely
different hardware and I'm guessing the panfrost one probably is as
well, so most likely I didn't need to remove those 2.
This is not a great report and maybe not helpful (sorry) as
unfortunately I cannot try and narrow it down further to a single patch
as this machine has to stay running now for a while. I just crudely
tried yanking those 4 to hopefully get rid of the error and get the
machine running again. Also I didn't go on to test whether the card
actually worked as expected, maybe the error is harmless after all,
though it doesn't look insignificant.
As the error was only output for the Bonaire card (the other two were
fine), below is lspci -vvv output for that card only in case it helps.
If anyone would like further info just let me know.
